IMPROVEMENT IN RECIPROCATING CHURNS.

Specification forming part of Letters Patent No. 197,898, dated December 4, 1877; application filed May 15, 1877.

To all whom it may concern Be it known that I, LEONARD GOON-ROB- ERTS, of Nunda, in the county of Livingston and State of New York, have made certain Improvements in Ghurns, of which the following is a specification:

This invention relates to certain improvements in churns; and consists of a novel construction and combination of parts, which will be fully hereinafter described.

In the drawings, Figure l is a side elevation in section. Fig. 2 shows the slide in the lid; Fig. 3, bottom-plan view of the dasher.

A represents the body of the churn, and B a central rod or post fastened to the lid 0 at the top, and setting in or on the bottom of the churn proper. On this post the dasher D works up and down.

The dash is made of four downwardly-projectin g, slanting, and spreading arms, mm (0, having vent-openings b b in each, said arms being attached to, at an angle, the central part c, which surrounds and works on the stationary rod B. This is operated up and down by a vibrating rod, E, pivoted at its lower end to the central dash-piece c, and at its upper end pivoted to an arm, cl, of the crank G. This crank and arm are arranged and operate in connection with an upright frame or post, H, attached to the top of the lid or cover 0 of the churn. 1

Both the vibrating rod E and crank-arm d have graduating-holes c e therein, to give a long or short stroke to the dasher, as may be required.

The vibrating rod E, protruding and workingthrough the lid 0, necessitates a long opening or slot, f, therein, and through which the cream, &e. would splash out. To prevent this I arrange a slide, (see Figs l and 2,) moving in a slot on the under side of the lid, and

also on brackets or supports it h, said slide having an opening, 5, in the center just wide enough to inclose the vibrating rod B, so that it shuts off the slot-opening fin the cover, and, with the movement of the rod, it slides back and forth, offering no impediment to the Working, but preventing the contents of the churn being splashed through at every movement of the dasher. This is an important feature.

The construction of the dasher is thought Y LEONARD G. ROBERTS.
